INVENTOR ATTORNEY Patented Apr. 14, 1931 HERBERT W. SEMISCH, OF THIEF RIVER FALLS, MINNESOTA wrivnow-ornnnrme MECHANISM Application 1 filed May 9,

This invention relates to vehicle'doors,and particularly to windows and screens for motor vehicle doors.

"The general object of the invention is to provide a pair of window glasses and a screen for a single vehicle door, the screen being movable independently ofthe window glasses which may be moved for raising and lowering the same inunison by a single crank when a. storm glass is desired, or only the main glass may be operated while the storm or auxiliary glassis retained in normal or lowered position.

.A further object of the invention is to provide a combination screen and storm window 3 iii un tfor doors or the like of motor vehicles, that is simple in construction, inexpensive to manufacture and efficient in operation and service. 7. a

1 This invention also consists in certain other features of construction and in the combination and arrangment. of the several parts, to bediereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an inner view of a vehicle door constructed in accordance with my invention and with parts broken away to illustrate the application thereof.

Figure 2 is a vertical sectional view taken longitudinally through the door as shown in Figure 1.

Figure 3 is an enlarged view showing the glasses and screen in normal posit-ion and the parts arranged for operating the main glass only.

Figure 4 is a similar view with the parts in position for operating both glasses.

Figure 5 is a fragmentary sectional View showing one of the screen fastening elements in engagement with the screen.

Referring to the drawings in detail, the letter A indicates the frame of a vehicle door which includes the usual metallic outer face and inner face B which is provided with a 1928. Serial No. 276,338.

slot arranged vertically therein as best shown in Figures 3 and 4 of the drawings.

Each of the side members of the frame is provided with parallel guides 1, 2 and 3. The guide 1 is adapted to accommodate the storm or auxiliary glass 4, the guide 2 the screen 5 and the guide 3 the main glass 6.

iki-ranged above the bottom of the door frame and having its ends secured in the side members thereof is a cross strip 7 having secured to its upper surface in any well known manner, an elongated block 8 preferably formed from rubber or other like resilient material.

Arranged between the side members of the frame are the usual window pieces 9 and 10 whichare arranged in spaced relation and upon opposite sides of the guides as shown. Depending from the window piece 9 and secured thereto is a bracket 11 which terminates at its lower end in a bearing 12 to accommodate the inner reduced end of a stub shaft 13 of a handle 14. The inner reduced end is mounted for rotation and is headed as shown to prevent lateral displacement as will be apparent. The stub shaft is square in cross section for the major portion of its length and extends through an opening in the inner face of the door for the purpose of disposing the handle accordingly. Depending from the windowv piece 10 is a bracket 15 having secured therein a pin 16 which has mounted for rotation thereon a sprocket 17 which cooperates with a sprocket 18 secured to one end of a shaft 19 arranged in the cross strip 7 as clearly shown in Figure l of 'the drawings. The sprockets have trained thcreabout a sprocket chain 20 which has secured to some of its links a headed pin 21 adapted to be disposed at all times in an opening 22 arranged in and centrally of the base strip 23 of the main glass 6 whereby When the sprocket chain is moved, the main glass will be moved accordingly.

Mounted for simultaneous movement on the square in cross section portion of the stub shaft 13. is a sprocket 25 while similarly mounted on the shaft 19 is a sprocket 26 cooperating with the sprocket 25 for receiving a sprocket chain 27 and these sprockets 25and of the door and disposed in parallelism with respect'to each other, are studs 33 which have slidably mounted thereon a shifting strip 34 which terminates in arms disposed about the shafts 13 and 19, as best shown in Figure 1 of the drawings and arranged in contacting engagement with the sprockets and 26 for moving the sprocketsfagainst the tension of the coil springs 28. This movement is accomplished by the cam member disposed in constant'engagement with the shifting strip 7 but is eccentrically mounted. and-pivotally se cured as at 36. A handle 37 is formed with the cam member which is disposedin the slot of the inner face B, whereby the handle 37 will always be in convenient reach of the occupant of the vehicle having the novel winv dow unit arranged'therein.

The base pieces for the respective glasses normally repose upon the block 8 and a screen 38is arranged between these glasses and is likewise provided with a base piece 39 normally disposed upon the block. The screen is operated through the medium of a handle piece 40 secured to the upper end of the screen as shown in Figure 1 and said screen is held in its open position by spring pressed cups 41 arranged in the side members of the frame and being adapted to be received in depressions 42 formed in the side members of the screen as suggested'in Figure 5 of thedrawmgs.

From the above description and disclosure of the drawings, it will be-obvious that re gardless of the position of the parts, the main glass willbe operated upon the movement of the handle 37, but when itis desired to move the storm or auxiliary glass, the cam member is positioned as shown in Figure 4 for shifting the shifting strip 34 to its operative position for the purpose of disposing the headed pin of the sprocket chain 27 in the opening30 whereby'upon movement of the handle, both of the glasses will be operated in unison. lthe screen isoperated by the handle piece 40 as above set forth.

It is thought from the foregoing description that the advantages and novel features of my invention will bereadily apparent.

I- desire it to be understood that I may make changes in the construction and in the I combination and arrangement of the several parts, provided that such changes fall withm'the scope of the appended claims.

What I claim is: y 1. A lift device for the window glass of motor vehicle doors and the like comprising a cross strip disposed adjacent the bottom of the window pocket therein, a shaft journaled upon the strip having sprockets fixed upon the pro ecting ends thereof, companion sprockets located adjacent the mouth of the window pocket being joined with the first mentioned sprockets through the instrumentality of endless chain connections,

frames for the window glasses having openings, pins carried by and operable in conjunction with the chains and projected within said openings, and means carried by and operable in conjunction with the door to shift the chains, sprockets and pins therefor with relation to the frames.

2. A. lift device for the window glass of motor vehicle doors and the like comprising a cross stripdisposed adjacent the bottom of the window pocket therein, a shaft journaled upon the strip having sprockets upon the projecting ends thereof, companion sprockets located adj acent'the mouth of the Window pocket bein joined with the mentioned sprockets through the instrumentality of endless chain connections, frames for the window glasses having openings, pins carried by and operable in conjunction with the chains and projected within said openings, a strip mounted for lateral shifting movement within the vehicle door, and an eccentric operating member-carried by the door engageable with the shifting strip to facilitate engaging and disengaging one of the pins with the adjacent frame.

In testimony whereof I affix my signature.
